Answer:
f(x) = 300,000(1.05)^x
Step-by-step explanation:
Use the exponential growth equation:
f(x) = a(1 + r)^x
Plug in 300,000 as a, since it is the original population:
f(x) = 300,000(1 + r)^x
The city's population is growing at 5% each year, so plug in 0.05 as r:
f(x) = 300,000(1 + 0.05)^x
f(x) = 300,000(1.05)^x
So, the function for the population growth is f(x) = 300,000(1.05)^x
It's 0 because 10+10 = 20 then subtract 20 and you get zero.
Answer:
X+Y is greater then or equal to 8
Step-by-step explanation:
In total she wants to sell <u>at le</u><u>ast</u> 8 items which implies shes willing to sell more (so greater or equal to) then it's adding X+Y bc those are the items that she is selling
The sum of a number and 2
x + 2
is twice the number
2x
answer
<span>x + 2 = 2x</span>
